Billionaire businessman and presidential candidate Donald Trump recently received a letter from Steven Tyler, front man for the rock band Aerosmith, but it wasn’t good news.

Instead, it was a letter from Tyler’s lawyers, demanding that Trump’s campaign stop using the Aerosmith song “Dream On” during its events, according to the Associated Press.

The letter from Tyler’s attorneys stated that Trump does “not have our client’s permission to use ‘Dream On’” as it “gives the false impression that he is connected with or endorses Mr. Trump’s presidential bid.”

Attorney Dina LaPolt was sure to note that Tyler, a registered Republican, had no problem with Trump personally or politically, but said the issue centered on a lack of permission and copyright infringement.

This isn’t the first time Trump has found himself at odds with musicians over the use of songs by his campaign.

Trump used Neil Young’s classic “Rockin’ in the Free World” during his campaign’s kickoff. But according to Fortune magazine, the far-left liberal Young demanded he stop using it. Young, a Canadian, also declared his support for Democrat presidential candidate and socialist Sen. Bernie Sanders.

Likewise, Trump found himself afoul of the band REM after using the song “It’s the End of the World As We Know It (And I Feel Fine).”

But not to worry. There are still plenty of songs available for Trump’s use. We suspect Ted Nugent might be willing to make one available for the Trump campaign.
